Societies and shows. -The dahlia is one of about a dozen genera of plants whose horticultural value has been attested by permanently successful special societies. There are national dahlia societies in England and America. Dahlia shows are usually held the second or third week in September. On December 21, 1906, the New England Dahlia Society was chartered; this Society led to great advancement in the dahlia, holding an annual exhibition in Boston, and issuing monthly a paper known as the "Dahlia News." Great interest was fostered, and in 1913 its membership list included nearly every state in the Union, and six foreign countries. At the present date of writing the New England Dahlia Society is considering the adoption of a new charter, whereby it can become the National Society. Other societies devoted to the welfare of the dahlia have been recently formed; principally "The Dahlia Association of Seattle," "Tacoma Dahlia Society," "Inter-town Dahlia Association" in Connecticut.
